I would like to show my advent calendar made with many different materials:
shiny items
rustling elements
corrugated cardboard
paper balls with Velcro
and train numbers to sign days:
I also have a skill I bought for my son, but not LEGO, because it is swallowed. I bought her a coloring, and can be opened in the same way as the traditional Advent calendars. In any event, when he got mad and very fond. If you are interested you can check here.
